As wireless communication network is a public network, the lte m2security and reliability of data transmission is particularly important. The module's wireless channel interference detection, data transmission security guarantee and other mechanisms ensure high security requirements. Embedded module after the car networking also has the following applications.

Emergency call

The communication module and positioning products are integrated into the vehicle system, so that when an accident occurs, information about the accident site is first obtained for timely rescue. When interference is detected, the communication module sends an alarm signal to the microcontroller and reports the interference in the cellular network.

Stolen vehicle for tracking and retrieval learning function

Car anti-theft management system provides a strong guarantee to reduce the development of car theft case studies in countries around the world, and the demand will also increase greatly. The design of anti-theft tracker products for electric vehicles and motorcycles is also in great demand in different countries.

Fleet management

For some large vehicles, excavators, concrete vehicles, logistics vehicles, etc., how to ensure the operation within the specified time and place is a great concern for operating companies. On-board technology can automatically access these vehicles to the company's service platform to control them effectively.

Personnel Positioning

GPS positioning is gradually being applied to real-time monitoring and management of personnel to ensure the safety of personnel and achieve reasonable management. For special environment, when the GPS signal is blocked, the communication module can also achieve positioning through special base station positioning method, which plays a good role in positioning assistance.

Telematics promotes the development of wireless module

Wireless module structure can be divided into enterprise LAN module (WiFi, Zigbee, Bluetooth), cellular module (2G/3G/4G/5G) and LPWAN module (NB-IoT, LoRa, etc.) through according to data communication network technology mainly, different technologies as well as corresponding to a different application research scene, at present, China's wireless module shipments reach the largest amount of non-cellular module, followed by location analysis module and cellular mobile communication module.

High price is the main limiting factor for the introduction of 4G/NB-IoT modules. Currently, hundreds of millions of IoT devices are still using 2G networks. In order to quickly reduce terminal prices and promote the development of the IoT industry, operators have proposed subsidy policies for the corresponding wireless module terminals.

At the Global Partner Conference, the operator announced the launch of a special subsidy of 2 billion RMB for IoT, hoping to further reduce the terminal cost and accelerate the maturity of the industrial terminal side. Among them, 1 billion is used for NB IoT, with a maximum subsidy rate of 80%; 1 billion is used for 4G IoT module subsidy, with a maximum subsidy rate of 50%.

Operators NB-IoT also in the third quarter of last year in the country's 11 provinces for trial commercial first-line work city development to achieve full coverage of urban areas, in May this year began to NB-IoT module can be analyzed and tested through the audit, plans to focus mainly on data collection.

Wireless communication module as an important part of the IoT hierarchy, in the automotive networking market demand, will certainly drive the development of the industry.

What are NB1 and NB2?

An improved variant of the LTE Cat NB1 standard is LTE Cat NB2 (NB-IoT). A new device category named NB2 and an improved NB-IoT protocol were both introduced by 3GPP in Release 14. The LTE Cat NB1 standard has been upgraded to this one.

LTE Cat A: What is it?

One of the key elements of LTE-Advanced, also known as LTE-A, is carrier aggregation. A 4G service's numerous bands are used through carrier aggregation to boost data transfer rates.

Which LTE band is the best?

Spectrum Band 3 at 1800 MHz. Using 1800 MHz (Band 3) frequency, 327 LTE or LTE-Advanced networks are active. More LTE networks than any other frequency band have been installed at 1800 MHz (band 3). Currently, Band 3 is commonly utilized across Europe, Asia, MEA, and some South American nations as well.

How fast can LTE travel?

Comparison of 4G LTE and With peak download speeds approaching 50 Mbps, Verizon's 4G LTE wireless broadband is ten times faster than 3G. It can handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps.
